[Elecraft] KPA500 - just 500 watts?

[juergen]

Hi Paul

Thats what I am  more interested in, the IMD performance of the future KPA500.

I own a Harris RF355 that I  would like to replace with a solid state amp.
I use this AMP in my remote station. It is a maintenance headache  with limited integration potential. 

Unfortunately non of the solid state offerings on the market have acceptable IMD performance. I seriously doubt that there will ever be a solid state amplifier manufactured for the ham market that will approach the IMD performance of the the Harris RF355 with the single 3cx800.

I wish Acom would produce a Autotune amplifier that uses  a pair of 3cx800PX's At least the IMD performance would be a certainty.

I dont know what devices the KPA500 uses?
